Investor profile | Builders Republic
About
NJJ is the personal holding company of Xavier Niel, founder of Iliad (Free), created in Paris in 2010; NJJ Capital is its investment company, and Anthony Maarek, a former Deloitte partner, is the CEO. The holding invests its own capital, without external subscribers or limited-duration funds, and reported €15.35 billion in assets at the end of 2024, excluding Iliad, according to its accounts analyzed by Le Point. Its stakes in telecom operators (Salt in Switzerland, eir in Ireland, Monaco Telecom, DVL Telecom in Ukraine) account for 85% of its 2024 revenue. No thesis or check size range published. NJJ ranges from pre-seed (20% of Acheel at its launch, $220M round for H Company) to late-stage rounds ($175M for Morpho in 2026), and sometimes co-leads (PayFit in 2016, Poolside in 2023). Portfolio: Alan, PayFit, Poolside, Morpho, H Company, Nabla, Vsora, Acheel, MWM, CGTV, and TikTok's American joint venture. For a founder, NJJ is not approached like a fund: no website or application channel, and €150k checks go through Kima Ventures, housed in the same holding. NJJ is more likely to be found in rounds of several tens of millions, alongside institutional funds.
